Answer 1

Resposta:

Explicação passo-a-passo:

a) (-16) : ( 4) + 17 = - 4 + 17 = 13.

b) 3 . ( - 9) + 14 = - 27 + 14 = 13.

c) – 30 + 6 . ( - 1) = - 30 - 6 = - 36.

d) (8 + 5) : ( 2 – 15) = 13 : ( – 13) = - 1.

e) ( +2) . ( -6) + (-5) . ( -3) = - 12 + 15 =  3.

f) (-3) . ( -8) + (-2).( -6) = 24 + 12 = 36.

g) 40 : ( -1) + (-8) – 12 = - 40 - 20 = - 60.

h) 16 : ( -2) + 9 . ( -1) = - 8 - 9 = - 17.

i) 81 + (-20) . ( +4) = 81 - 80 = 1.

j) (-4) . (-7) – 30 = 28 - 30 = - 2.

k) - 23 – (-6) . ( +3) = - 23 + 18 = - 5.

l) 19 – ( -4) . ( +5) = 19 + 20 = 39.

m) 7 . (-3) – 9 . (-6) + 11 . (-2) = - 21 + 54 - 22 = 11.

n) 5 . ( +11) – 37 – (-2) . ( +14) = 55 - 37 + 28 = 46.

o) -10 – 20 : (+4) = - 10 - 5 = - 15.

p) ( +30) : ( -6) + ( -18 ) : ( - 3) = - 5 + 6 = 1.

q) 7 : ( -7) + 2 . ( -6) + 11 = - 1 - 12 + 11 = - 2.

r) 2 + ( -75) : ( -5) – 4 . ( -1)= 2 + 15 + 4 = 21.
